Inline comments:
In `@docs/ios-network-reliability.md`:
- Around line 1-30: Add the matching Japanese localization for the iOS network
reliability workload through the repository’s established documentation
localization path, preserving all scenarios, commands, options, and pass
criteria from the English source. Ensure the Japanese source is updated
alongside the English Markdown.
In `@ios/cmuxPackage/Sources/cmuxFeature/MobileIrohRuntimeComposition.swift`:
- Around line 1860-1878: Update the three transportLANDiscovery DiagnosticEvent
calls in the LAN discovery outcome handling to include the peer alias as their
surface, using target.deviceID through the existing alias-resolution mechanism.
Apply this consistently to the found, notFound, and policyDenied outcomes while
preserving their existing outcome values and counts.
In
`@Packages/iOS/CmuxMobileRPC/Sources/CmuxMobileRPC/MobileRPCTransportConnectEvent.swift`:
- Around line 18-19: Update the public event enum’s API around the connected and
cancelled cases to preserve source compatibility for existing exhaustive
switches and associated-value patterns. Use an API-versioning or compatibility
approach that retains the existing connected case contract while exposing
cancellation without forcing current consumers to change.
In
`@Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShell/MobileShellComposite`+ManualAttachTicket.swift:
- Around line 123-125: Update the transportConnectDiagnosticObserver call in the
manual attach probe flow to pass nil for peerID instead of
probeTicket.macDeviceID, since no authenticated Mac ID is available; preserve
peer attribution only when an authoritative typed transport or session record
provides it.
In
`@Packages/iOS/CmuxMobileShell/Tests/CmuxMobileShellTests/PresenceDiscoveryInvalidationTests.swift`:
- Around line 100-108: Update the affected tests in
PresenceDiscoveryInvalidationTests to clean up both the temporary SQLite
directory and the per-test UserDefaults suite during teardown, reusing the suite
and directory identifiers tracked by the test setup. Ensure cleanup runs after
each test, including when the test body fails.
In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxConnectivityEngine.swift`:
- Around line 563-568: Update the failed-session reporting around
CmxConnectivityEngine’s noteDialFailure call to use the effective dial plan
actually selected by CmxIrohClientSession, including any
contextWithPrivateFallback replacement, rather than the stale context.dialPlan.
Propagate that final plan or move noteDialFailure to the point where the final
plan is chosen, while preserving the existing failure classification.
In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohClientSession.swift`:
- Around line 60-61: Update CmxIrohClientSession initialization and
CmxConnectivityEngine call sites to accept and store the authoritative peer
session alias, removing the DiagnosticCorrelation().handle(for:
targetIdentity.endpointID) derivation; ensure all connection events reuse the
same alias as CmxConnectivityPeerSession, including the affected lifecycle and
close paths.
In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohRegistryContextProvider.swift`:
- Around line 389-404: Update the staleness-recording paths
invalidateVerifiedDiscovery and markDiscoveryStale to detach any existing
sharedDiscoveryTask when stale evidence is recorded, allowing the next
sharedDiscover call to start a fresh broker request instead of joining the
pre-invalidation task. Preserve sharedDiscover’s existing cleanup behavior and
ensure the stale marker remains authoritative until the replacement request
completes.
- Around line 241-254: In the fresh resolve retry around resolveContext,
snapshot lanAuthorities before the call and restore that snapshot in the catch
path before returning resolved, so failed validation cannot remove authorities
needed by contextWithPrivateFallback. Keep the existing resolved-context
fallback behavior unchanged.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohConnectionDiagnosticRecorderTests.swift`:
- Around line 109-129: Update the diagnostic event assertions in
CmxIrohConnectionDiagnosticRecorderTests to explicitly validate the
transportCloseAttribution event at index 4, including its clamped application
error code, rather than reading the subsequent transportCloseReason event. Keep
the existing transportCloseReason assertions for index 5 unchanged.
In
`@Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/DiagnosticEventPresentation.swift`:
- Around line 815-833: Update cancellationReasonName and remoteCloseReasonName
so their unknown-value default strings interpolate the raw integer using \(raw)
rather than literal ((raw)) text, and add regression tests covering unknown
cancellation and remote-close values with the expected payloads.
In
`@Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/DiagnosticReport.swift`:
- Around line 357-362: Update the diagnostic attempt-ID decoding around the
guard in the relevant DiagnosticReport method so transport dial session-linked
events read the attempt ID from slot a, while other transport dial events
continue reading slot c. Preserve c as diagnosticLinkedSessionID, and add a
regression test covering different attempt and session IDs.
In
`@Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/Resources/Localizable.xcstrings`:
- Around line 5704-5813: Add catalog entries for the nine keys referenced by
DiagnosticEventPresentation.label(for:): diagnostics.field.outcome,
editableFocused, created, publicPaths, privateFallbackPaths, join,
configuredAddresses, hints, and leg. Each entry should use manual extraction
state and provide translated en and ja string values consistent with the
existing diagnostics.field entries.
In `@Packages/Shared/CMUXMobileCore/Tests/CMUXMobileCoreTests/AppLogTests.swift`:
- Around line 300-305: Add assertions in the existing
DiagnosticEventCode.appLogDomain classification tests for
transportDialSessionLinked, transportDialCancelled, and transportCloseReason,
verifying each maps to .network alongside the other transport events.
In
`@Packages/Shared/CMUXMobileCore/Tests/CMUXMobileCoreTests/DiagnosticEventPresentationTests.swift`:
- Around line 306-316: Update the cancellation presentation assertion in the
diagnostic event test to compare cancelled.fields against the complete expected
field list, including cancellation, peer, duration, and attempt values, rather
than checking only the cancellation field.
In
`@Packages/Shared/CMUXMobileCore/Tests/CMUXMobileCoreTests/DiagnosticLogTests.swift`:
- Around line 310-312: Extend the DiagnosticEventCode raw-value contract test to
assert the exact expected values for codes 71 through 76, alongside the existing
assertions for transportDialSessionLinked, transportDialCancelled, and
transportCloseReason. Use the corresponding six earlier event-code symbols and
preserve the append-only numbering checks.
In `@scripts/analyze-ios-network-log.py`:
- Around line 198-204: Update the background-gap validation around
expected_background_seconds so a positive expectation fails when background_gaps
is empty, while retaining the existing maximum-gap comparison for observed gaps.
Add a regression test covering a successful connection with no lifecycle events
and verify it reports failure.

| # iOS network reliability workload | ||
|
|
||
| Run this on the tagged iOS build and export cmux-network.log after each | ||
| scenario. The export contains peer aliases and session IDs, never Mac IDs or | ||
| addresses. | ||
|
|
||
| 1. Cold launch: terminate cmux, launch it, attach one Mac, and wait until the | ||
| terminal is usable. Record the time from launch to the first usable terminal. | ||
| 2. Background resume: leave the connected app in the background for eight | ||
| minutes, return to it, and wait for a usable terminal. This exercises the | ||
| startup recovery owner and the suspended-process deadline guard. | ||
| 3. Liveness: keep the terminal open, let the liveness watchdog resubscribe | ||
| (or use the existing debug liveness trigger), and verify that recovery has | ||
| one recovery ID and one admitted session. | ||
| 4. Single and multi-Mac: repeat with one Mac, then switch between two Macs and | ||
| return to the first. The report must not show two active physical sessions | ||
| for one peer. | ||
|
|
||
| Check an export with: | ||
|
|
||
| ~~~sh | ||
| ./scripts/analyze-ios-network-log.py /path/to/cmux-network.log \ | ||
| --expect-background-seconds 480 | ||
| ~~~ | ||
|
|
||
| Use --json for a machine-readable artifact. A passing run has at least one | ||
| usable RPC connection, no duplicate active sessions per peer, and an observed | ||
| background gap of at least eight minutes. The output also reports usable | ||
| latency, cancellation reasons, recovery outcomes, direct-dial stages, path | ||
| changes, and liveness resubscriptions. |

Attach the peer alias to these transportLANDiscovery events.
CmxIrohRegistryContextProvider records the same event code with surface: DiagnosticCorrelation().handle(for: expectedDeviceID). These three outcomes carry no surface, so a log reader cannot attribute a found, notFound, or policyDenied result to a Mac. target.deviceID is available in this closure, and the alias keeps the raw id out of the log.
♻️ Proposed refactor
lanFallback: { [diagnosticLog] target, bindings, rendezvous in
guard let lanPeerDiscovery else { return [] }
+ let peerAlias = DiagnosticCorrelation().handle(for: target.deviceID)
switch await lanPeerDiscovery.discover( diagnosticLog?.record(DiagnosticEvent(
.transportLANDiscovery,
+ surface: peerAlias,
a: DiagnosticLANDiscoveryOutcome.found.rawValue,
b: hints.count
))Apply the same surface: peerAlias argument to the notFound and policyDenied events.

Do not assign every manual probe to one peer.
probeTicket.macDeviceID is the fixed value "manual-ticket-request". This records every owned manual attach probe under the same peer alias. Unrelated Macs then appear as one peer in recovery diagnostics.
Pass nil until an authenticated Mac ID exists. Do not report a synthetic constant as peerID.

- transportConnectObserver: transportConnectDiagnosticObserver(
- peerID: probeTicket.macDeviceID
- ),
+ transportConnectObserver: transportConnectDiagnosticObserver(

Remove the temporary directory and the UserDefaults suite after the test.
The test creates a temporary directory with an SQLite store and a per-test UserDefaults suite, then leaves both in place. Each run adds a directory and a defaults suite that never get reclaimed.

Assert the complete cancellation payload.
The test checks only the cancellation field. A presentation regression can omit peer, duration, or attempt without failing.

Fail when the required background gap is absent.
If --expect-background-seconds is positive and the export has no complete background-to-active pair, this condition adds no failure. A connection-only export can then return PASS without the required background observation.
Require at least one observed gap before comparing its maximum. Add a regression test with a successful connection and no lifecycle events.
Proposed fix

- if max(background_gaps) < expected_background_seconds:

In `@ios/cmuxPackage/Sources/cmuxFeature/MobileIrohRuntimeComposition.swift`:
- Around line 2561-2562: Update the macDiscovery computation in
MobileIrohRuntimeComposition to use one shared, typed discovery-refresh result
from the live discovery flow rather than reading cached routeCatalog candidates
directly. Preserve the mapping of successful non-empty results to .found,
successful empty results to .missing, and refresh/service failures to
.unavailable; retain the result so related reporting uses the same refreshed
source. Add coverage for stale, empty, and unavailable discovery states.
In
`@Packages/Shared/CMUXMobileCore/Sources/CMUXMobileCore/DiagnosticEventPresentation.swift`:
- Around line 367-371: Remove duplicate case patterns from
DiagnosticEventPresentation.title(for:) around the affected mappings, preserving
one mapping for each diagnostic event code. Also remove the repeated
.transportDialLegFailed entry from codesWithFailureB while keeping its single
intended occurrence.
- Around line 296-312: The event presentation logic must keep the structured
field key as “surface” for all events; update the key assignment around
event.code so recovery and peer categorization does not replace it. If category
metadata is required, add it as a separate versioned field while preserving the
existing surface value and stable key consumed by TransportSentryReporter.

Summary\n\nConsolidate the four iOS network reliability actions into one implementation:\n\n- coalesce startup recovery behind one owner and replace stale recovery attempts safely;\n- enforce one physical Iroh session per peer, with serialized control ownership and safe redial;\n- add privacy-safe, correlated dial, recovery, path, cancellation, close-reason, peer-alias, build-tag, and SHA diagnostics;\n- refresh stale discovery before redial, single-flight broker discovery, and ship a repeatable log analyzer/workload guide.\n\nThe diagnostics deliberately keep raw endpoints, tokens, and error text out of exports. The analyzer reports dial latency, cancellations, recovery outcomes, background gaps, direct stages, liveness resubscriptions, duplicate peer sessions, and pass/fail thresholds.\n\n## Verification\n\n- swift build --scratch-path /tmp/netrel-build-core passed.\n- swift build --scratch-path /tmp/netrel-build-iroh passed.\n- swift build --scratch-path /tmp/netrel-build-rpc passed.\n- swift build --scratch-path /tmp/netrel-build-shell passed.\n- CMUXMobileCore focused diagnostics tests: 44 passed.\n- CmuxMobileRPC transport lifecycle tests: 4 passed.\n- analyzer unit tests: 2 passed.\n- git diff --check passed.\n\nThe Iroh SwiftPM test helper did not emit a completion result in the local environment after building its bundle, so the PR relies on the clean package build plus the focused suites above and hosted CI for the full test execution.
